Antimicrobials

Amoxicillin is an aminopenicillin antibiotic and is used for the treatment of various bacterial infections. It works by inhibiting the synthesis of bacterial cell wall mucopeptides, leading to cell lysis and death

Casein is a phosphoprotein, which is derived from milk. It originates primarily from cow's milk, where it constitutes about 80% of the total protein content. The mode of action for casein involves its ability to form a gel or clot in the stomach, which makes it highly efficient in nutrient delivery, especially the slow release of amino acids. This process is facilitated by its unique structural features, such as the presence of multiple phosphoryl groups that can bind calcium ions.

Sebuthylazine-2-hydroxy is a selective pre-emergent herbicide, which is a derivative of the sym-triazine compound family synthesized through chemical processes. It functions primarily as a soil-acting agent that inhibits photosynthesis by binding to the D1 protein in the photosystem II complex, thereby disrupting the electron transport chain. This biochemical action effectively curtails the growth of susceptible weed species by preventing their development, particularly annual grasses and broadleaf weeds.

STAADIUM™ GlucuroniZide is a targeted inhibitor of glucuronidase-producing bacteria, which is activated by E. coli-specific glucuronidase enzyme. Glucuronidases are enzymes catalysing the cleavage of complex carbohydrates and E. coli is a well-known producer. In complex cultures, E. coli strains often outcompete bacteria that present at lower titre and STAADIUM™ GlucuroniZide can help to selectively reduce the growth of E. coli. STAADIUM™ GlucuroniZide can be used in microbiome studies, food control, environmental safety, hygiene, and clinical diagnostics. More details can be found in the application notes document.

Inhibitor of protein synthesis; aminoglycoside

Anti-malarial quinine analogue; effective against Covid-19 infection in vitro

Anti-retroviral; HIV protease inhibitor

Cytarabine is also known as cytosine arabinoside (ara-C) and is a chemotherapy drug that works by inhibiting DNA synthesis. It acts as a nucleoside analogue, which is incorporated into the growing DNA chain during replication. Cytarabine combines a cytosine base with an arabinose sugar (1β-arabinofuranosylcytosine) and is an analog for human deoxycytosine. Cytarabine interferes with DNA synthesis as it is rapidly converted to cytosine arabinoside triphosphate, damaging DNA when cells are in the synthesis phase (S phase). Tumor cells which are highly mitotic and growing rapidly are therefore preferably targeted. Cytarabine also inhibits nucleotide reductase enzymes as well as nuclear polymerases, leading to interruption and inhibition of synthesis, strand breaks and cell death.

Anthracycline is a class of chemotherapy drugs, which are anthraquinone antibiotics derived from the bacterial genus Streptomyces. They exert their therapeutic effects primarily through intercalation into DNA, disrupting the function of enzymes such as topoisomerase II, thus preventing the transcription and replication processes in rapidly dividing cancer cells. Furthermore, they generate free radicals, leading to oxidative stress and subsequent cell damage. These mechanisms collectively result in apoptosis of malignant cells. Anthracyclines are utilized extensively in oncology for the treatment of various malignancies, including leukemias, lymphomas, breast cancer, and sarcomas. The efficacy of anthracyclines in inhibiting tumor growth must be balanced against their cardiotoxic potential, which is a significant consideration in their clinical use. This dual nature makes them both pivotal and challenging in chemotherapy regimens, necessitating careful management and monitoring throughout treatment.

Valinomycin is an ionophore antibiotic with action on potassium ion transport across cell membranes and is used for research on ion transport and as an antimicrobial agent.

STAADIUM™ PeptiZide L-Ala is a targeted inhibitor for L-alanine aminopeptidase-producing bacteria. The antibacterial activity of STAADIUM™ PeptiZide L-Ala is triggered by the enzyme L-alanine aminopeptidase, an enzyme located in the bacterial cell wall and is a characteristic of Gram-negative bacteria. L-alanine aminopeptidase has not been experimentally detected in Campylobacter species, anaerobic bacilli, Gram-positive and Gram-variable bacteria. More details in the application notes document.

Nitrocycline is a broad-spectrum antibiotic, which is a synthetic derivative of tetracycline with enhanced antibacterial properties. As a chemically synthesized compound, nitrocycline has been engineered to overcome resistance mechanisms common in bacterial pathogens. Its mode of action involves the inhibition of protein synthesis, achieved by binding to the 30S ribosomal subunit, effectively preventing the addition of new amino acids to nascent peptide chains. This binding action interrupts bacterial growth and replication, providing robust activity against both Gram-positive and Gram-negative bacteria.

Binds to 70S ribosomal subunit; inhibits translocation and induces miscoding

Amoscanate is an antiparasitic compound derived from synthetic chemical processes, which acts by disrupting the mitochondrial function of parasitic organisms. This compound intervenes in the energy metabolism of endoparasites, leading to their incapacitation and eventual death. Its action is selective for parasitic species, minimizing effects on the host organism.

Herbicidin K is a naturally derived herbicide, known for its biological origin from microbial fermentation processes. It is primarily sourced from certain strains of Streptomyces, a genus of Gram-positive bacteria notable for their diverse secondary metabolites. The mode of action of Herbicidin K involves the inhibition of key enzymatic pathways within target plants, leading to the disruption of cellular functions and ultimately plant death. This selectivity is particularly effective against broadleaf weeds, providing a targeted approach to weed management.

Ethambutol is an antimicrobial compound, specifically an antitubercular agent, which is a synthetic derivative of ethylenediamine. It is classified as a bacteriostatic agent that primarily targets Mycobacterium tuberculosis. The mode of action of Ethambutol involves the inhibition of arabinosyl transferases, enzymes essential for the polymerization of arabinogalactan, a critical component of the mycobacterial cell wall. By disrupting cell wall biosynthesis, Ethambutol effectively hampers the growth and proliferation of the bacteria.
